<stepping up on soap box>
I have a big problem with people who stalk threads such as this one and rate them terrible. That is a cowardly act of anonymous timidity. (note that is not a personal insult as I specifically reference the act and not the actor
If we have RC equipment it is because we purchased it from a vendor. To maintain that vendors acting honestly in their own name, making a single post to advise a group of people obviously interested in and enthusiastic about their product is "terrible" reveals seriously mistaken judgment.
I've never done business with Common Sense RC and don't know anything about the performance or customer service of that company. But they and other vendors of RC equipment do us a great service by providing the products we need to enjoy our hobby.
Cut them a break! Or if you have a legitimate gripe, make it honestly and do so openly like a human being. <steps down from soap box>
